Background of the Invention
[0001] This invention relates to a floatable toy and in particular a toy having the general
configuration of a boat comprising a raft portion and being floatable by virtue of
pontoons affixed to the raft.
[0002] Pontoon-supported boats for carrying passengers and cargo are, of course, well known
and their design and methods of manufacture are directed to the specific problems
encountered in fabricating such full size vessels. Examples of such designs are found
in the patent art in U.S. Design Patent D-123,501; U.S. Patent 3,426,716; U.S. Patent
3,063,398; U.S. Patent 2,394,764; and U.S. Patent 2,077,526.
[0003] It is also known to produce toy boats comprising pontoons, such prior knowledge being
exemplified by U.S. Patent 4,045,907.
[0004] The different problems associated with the design and manufacture of full size vessels
as compared to toy boats are well illustrated by the above referred to prior art.
In the case of full size vessels, such considerations as safety, strength, hydrodynamics
and the like are paramount. Accordingly, the means for fastening the pontoon to the
remainder of the vessel are all designed with these factors in mind. Thus, in U.S.
Patent 3,063,398 a T-shaped lug adapted to interfit with and anchor a clamp carried
by the body of the vessel is provided. In U.S. Patent 2,394,764 a complex arrangement
of saddle and flange means interconnected with tie rods and trim buckles is provided.
In U.S. 3,426,716 a split tube welded to a plate engages arcuate flanges depending
from the body of the vessel to secure the pontoon to the vessel.
[0005] In contrast with the aforementioned designs, water- worthiness and strength are not
the principle criteria in designing a toy boat. In many cases, the features which
provide such attributes are actually detrimental in a toy in that they represent sharp
edges and breakable elements which can be dangerous to a small, active child. Beyond
question, they do not lend themselves to high speed manufacturing processes which
are essential for the practical mass marketing of children's toys.
[0006] Thus, for example, in U.S. Patent 4,045,907 for a toy boat, the simple solution suggested
is to merely secure the pontoons to the body of the boat by gluing. The apparent simplicity
of this design notwithstanding, several drawbacks are associated therewith. In the
manufacturing process, the glue must be carefully registered and placed at the proper
location and only at the proper location. Deposition of excess glue must be avoided.
The drying process must be completed prior to further manufacture and packaging. All
these steps greatly slow the manufacturing process. Additionally, the choice of glue
for a toy boat to be used in a bathtub environment by a small child is extremely limited.
Such choice is constrained when it is considered that the toy will be employed in
hot soapy water which will tend to attack the glue seal. Needless to say, the issue
of toxicity will also eliminate many otherwise useful glues.
[0007] Accordingly, there is a need for an improvement in a toy boat of this kind which
is easy to assemble and avoids complex or dangerous elements.
Summary of the Invention
[0008] In accordance with this invention, a floatable toy is provided which obviates the
problems associated with the affixation of pontoons to a raft-like portion of the
toy and specifically, avoids the problems of complex connecting means, gluing or requiring
difficult assembly steps.
[0009] The floatable toy of this invention comprises a raft portion having longitudinally
extending edges and two pontoons which comprise floatable, generally cylindrically
shaped bodies, each having a longitudinal axis and each affixed to the raft adjacent
to a longitudinal edge with the longitudinal axis of the pontoons parallel to said
longitudinal edge. Means are provided for affixing the pontoons in such position to
the raft, these means comprising arcuate brackets extending from each of the longitudinal
edges. At least a portion of said brackets are adapted to cooperate with and interfit
into depressions in the cylindrical wall of the pontoons to present a positive means
for securing said pontoons to the raft portion.
[0010] Preferably, a plurality of brackets are provided extending from each of the longitudinal
edges of the raft with at least one of said brackets extending from the bottom portion
of the raft and at least another of said brackets extending from the top portion of
the raft to support the pontoon. It will be understood that as used herein the term
"top", with respect to the raft, refers to the surface of the raft facing out of the
water and the term "bottom", with respect to the raft, refers to the surface of the
raft facing into the water. In a first embodiment, the brackets are each provided
with a rib portion extending radially from the inner circumferential surface toward
the center of curvature of said brackets, the ribs being adapted to interfit into
the depressions in the cylindrical walls of the pontoons. In another embodiment, the
entire bracket interfits into the depressions in the cylindrical walls of the pontoons
to present a smooth cylindrical surface comprising said bracket and said cylindrical
walls of the pontoons.
[0011] In another aspect of this invention, the brackets are molded integrally with the
body of the raft and, owing to the selection of materials of construction and the
thickness of the brackets, have a slight degree of flexibility. Accordingly, the raft
portion and the pontoons may be molded separately. To assemble the floatable toy,
each pontoon may be axially aligned along one longitudinal edge and in front of said
raft portion in a position whereby the pontoon is rotated out of its intended position
of rotation when finally assembled. The pontoon may then be slid into position, parallel
to and adjacent to the longitudinal edge of the raft and past the brackets which,
owing to their flexible nature yield about the cylindrical walls of the pontoon. Because
the pontoon has been rotated out of its intended position, the depressions in the
cylindrical walls do not catch the brackets as the pontoon is slid into position.
Once in its proper axial position, the pontoon may be rotated to align the depressions
with the brackets which, again owing to their flexibility, will seat in the depressions
to complete the assembly.

Detailed Description of the Invention
[0013] Referring now to the drawings, Figs. 1-3 depict, in perspective assembled, perspective
exploded and transverse cross-sectional views, respectively, a floatable toy 10 embodying
the teachings of this invention.
[0014] The floatable toy 10 comprises a raft portion 12 having longitudinally extending
edges 14 and 16. The raft portion 12 of toy 10 may include various additional structure
to enhance the play value of the toy including, for example, a cabin like structure,
a mast, a wheel house or the like. As depicted in the drawings, the raft is provided
with a plurality of appertures or depressions 22. The floor of the depressions 22
are provided with drain holes 26. Various additional play-enhancing elements (not
shown) may be provided with the toy and adapted to fit within the appertures or depression
such as, for example, trays, cups, sprinkling cans or the like.
[0015] The toy 10 is provided with two pontoons 18 and 20, which are floatable and generally
cylindrically shaped bodies each having a longitudinal axis A-A and B-B, respectively.
In the assembled position as depicted in Figs. 1 and 3, the pontoons are affixed to
the raft, each adjacent to a longitudinal edge, with the longitudinal axis of the
pontoons parallel to said longitudinal edge. As best seen in Fig. 3, a portion 19
of the cylindrical surface of the pontoons is flattened to better fit against the
longitudinal edge of the raft.
[0016] In accordance with the teachings of the invention, the means for affixing the pontoons
to the raft comprise brackets extending from the longitudinal edges of the raft, at
least a portion of the brackets adapted for cooperating and interfitting with depressions
in the cylindrical walls of the pontoons. As shown in Figs. 1-3, upper brackets 28
are provided, integral with and extending from the top of the longitudinal edges of
the raft. Lower brackets 30 are provided extending from the bottom of the longitudinal
edges of the raft. Brackets 28 and 30 are arcuate to conform and fit closely to the
cylindrical walls of the pontoons. The brackets are provided with rib portions 29
which extend circumferentially along the inner surface of the brackets and depend
toward the center of curvature of the brackets. The term "inner surface" of the brackets
will be understood to mean that surface facing toward the surface of the pontoons
when the floatable toy is assembled.
[0017] The rib portions 29 of the brackets are adapted to interfit into depressions 32 and
34 provided in top and bottom portions of the pontoons. By so interfitting, the pontoons
are held securely to the raft portions.
[0018] In accordance with a further aspect of this invention, the design described herein
lends itself to a simple, commercially practical means for assembly. Firstly, the
brackets are selected to be constructed of a material and to have a thickness such
as to impart to the brackets a degree of flexibility. In this connection, such flexibility
shall mean that the brackets may be moved away from their intended position when the
toy is in its assembled condition and may be biased to return to its intended position
when the moving force is withdrawn.
[0019] To assemble the toy, each pontoon 18 and 20 is axially aligned along one longitudinal
edge, e.g., edge 16 and in front of the raft portion, e.g., the end portion 36 of
pontoon 18 is adjacent the raft corner 38. The pontoon at this point in the process
should be in a position of rotation about its axis away from its intended position
of rotation when the toy is fully assembled. Preferably the pontoon is rotated 10°
to 180° out of its intended position and more preferably 45° to 135°. The pontoon
is then slid into a position parallel to and adjacent to the longitudinal edge of
the raft and past the brackets and rib portions which, owing to their flexibility,
yield about the cylindrical walls of the pontoon. Because the pontoon has been rotated,
the depressions in the cylindrical walls do not interfere and catch the rib portions
of the brackets as the pontoon is slid into position. Once in the proper axial position,
the pontoon may be rotated to align the depressions with the rib portions of the brackets
which, again owing to their flexibility, will seat into the depressions and present
the assembled pontoon.
[0020] Fig. 4 depicts the partially assembled toy, in a transverse cross-sectional view
similar to that of Fig. 3, at a point in the assembly wherein pontoons 18 and 20 have
been aligned with longitudinal edges 16 and 14, respectively, and the brackets 28
and 30 are out of alignment with depressions 32 and 34 (not shown). As shall be understood
from the above discussion, by now rotating the pontoons about their longitudinal axes,
the depressions may be brought into alignment with the bracket and the brackets will
seat therein, reducing the toy to the assembled position shown in Figs. 1 and 3.
[0021] Referring now to Figs. 5 and 6, illustrated therein are perspective and transverse
cross-sectional views of an alternate embodiment for the floatable toy of this invention.
[0022] The floatable toy 40 again comprises a raft portion 42 having longitudinally extending
edges 44 and 46. The toy is provided with two pontoons 48 and 50 having the same general
shape as those described in connection with Fig. 1. Brackets 52 and 54 are provided
extending from longitudinal edges 44 and 46 of the raft portion 42, but unlike those
of Fig. 1, the brackets of this embodiment are not provided with depending ribs. Instead
the inner surface of brackets 52 and 54 are smooth. The pontoons 48 and 50 are provided
with depressions 56 and 58 adapted to have the entire brackets 52 and 54 interfit
therein. The depth and shape of the depression are provided such that when the brackets
are interfitted and the floatable toy is in its assembled position, the brackets and
the cylindrical walls of the pontoons will present a smooth cylindrical surface.
[0023] It will be understood that while the embodiments shown in the drawings illustrate
two top brackets and one lower bracket, many other combinations are possible and will
still meet the design critera prescribed herein. Thus, for example, one top bracket
and two bottom brackets will be effective. Similarly, the brackets may be of uneven
size and, in some instances, the top bracket may simply be elongated and only one
will suffice. In the preferred embodiments, a plurality of brackets are employed with
at least one of such being a top bracket and at least another being a bottom bracket.
Needless to say, whatever the configuration of the brackets, the depression in the
walls of the pontoons may be varied to conform thereto.
[0024] A wide choice of materials are suitable for use as the materials of construction
for the toy including, for example, metals, water proof paper or boards, or even,
in part, wood. Preferably however, the materials of choice are polymers which exhibit
thermoplastic behavior, e.g., "plastics" such as polyolefins, e.g., polypropylene
or polyethylene. Preferably the raft portion and its extending brackets are molded
together using injection molding techniques. The pontoons are preferably molded by
utilizing blow molding techniques, particularly when the raft portion is floatable
by virtue of the pontoons being hollow.
